<h3>概述</h3>

    <p>该模块只有在远程主机上运行了<a href="http://www.ietf.org/rfc/rfc1413.txt">RFC 1413</a>兼容的守护进程的情况下才能查询连接者的身份。</p>
</div>
<div class="top"><a href="mod_ident.html#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="directive-section"><h2><a name="IdentityCheck" id="IdentityCheck">IdentityCheck</a> <a name="identitycheck" id="identitycheck">指令</a></h2>
<table border="1" cellpadding="0" cellspacing="0" bordercolor="#AAAAAA" class="directive">
<tr><th><a href="directive-dict.html#Description">说明</a></th><td>启用对远端用户的RFC1413身份鉴定的日志</td></tr>
<tr><th><a href="directive-dict.html#Syntax">语法</a></th><td><code>IdentityCheck On|Off</code></td></tr>
<tr><th><a href="directive-dict.html#Default">默认值</a></th><td><code>IdentityCheck Off</code></td></tr>
<tr><th><a href="directive-dict.html#Context">作用域</a></th><td>server config, virtual host, directory</td></tr>
<tr><th><a href="directive-dict.html#Status">状态</a></th><td>扩展(E)</td></tr>
<tr><th><a href="directive-dict.html#Module">模块</a></th><td>mod_ident</td></tr>
<tr><th><a href="directive-dict.html#Compatibility">兼容性</a></th><td>Apache 2.1以后从服务器核心中移出到该模块</td></tr>
</table>
    <p>当客户端运行了identd或类似程序时，此指令将决定是否为每个链接记录<a href="http://www.ietf.org/rfc/rfc1413.txt">RFC 1413</a>兼容的远端用户名。这些信息将记入访问日志中(使用"<code>%l</code>"<a href="mod_log_config.html#formats">格式字符串</a>)。</p>

    <div class="note">此信息除了用于基本的跟踪以外是不应该多加信任的。</div>

    <p>因为对每个请求都会进行这样的查询，所以这样设置可能会使您的服务器访问出现严重的延迟。当涉及到防火墙或代理的时候，每次查询都会因为可能的失败而对每次点击增加<code class="directive"><a href="mod_ident.html#identitychecktimeout">IdentityCheckTimeout</a></code>秒的延迟。所以一般来说对于公网上的服务器这个指令并不是很有用。</p>

</div>
<div class="top"><a href="mod_ident.html#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="directive-section"><h2><a name="IdentityCheckTimeout" id="IdentityCheckTimeout">IdentityCheckTimeout</a> <a name="identitychecktimeout" id="identitychecktimeout">指令</a></h2>
<table border="1" cellpadding="0" cellspacing="0" bordercolor="#AAAAAA" class="directive">
<tr><th><a href="directive-dict.html#Description">说明</a></th><td>设置ident请求超时</td></tr>
<tr><th><a href="directive-dict.html#Syntax">语法</a></th><td><code>IdentityCheckTimeout <var>seconds</var></code></td></tr>
<tr><th><a href="directive-dict.html#Default">默认值</a></th><td><code>IdentityCheckTimeout 30</code></td></tr>
<tr><th><a href="directive-dict.html#Context">作用域</a></th><td>server config, virtual host, directory</td></tr>

<tr><th><a href="directive-dict.html#Module">模块</a></th><td>mod_ident</td></tr>
</table>
    <p>该指令设置了ident请求的超时时间。默认值"30"(秒)也是<a href="http://www.ietf.org/rfc/rfc1413.txt">RFC 1413</a>的推荐值，这主要是考虑到可能的网络延时。当然，你也可以根据你自己的网络状况进行调整。</p>
